Very impressed with the simple Green help and service.
Simple Green Aviation Extreme arrived Saturday.
Radiator cleaned and test ridden today. I tried to ride similar lanes as when it got the six bars and it was also the same ambient temperature of 22.5c.
Result stayed at 3 bars when moving in clear air and no more than 4 bars in traffic and some high hedged lanes in 3rd at about 40mph but came down to 3 bars when moving freely on more open road.
I dampened the rad with a water spray bottle and brushed the neat solution onto the fins and then 50/50 mix from the foamer bottle ( glad I bought it) and also brushed that in, had a cuppa and washed with my little gizzmo of squashed copper central heating pipe with an 8th inch hole in it and attached it to my garden hose. This allows you to get behind the rad and run the single jet along the rows of fins.
Do the back first of course. I was amazed at the grit thrown onto my front mudguard.
All in all a success I think. Link attached.
